Can't quality setting on Quicktime in AME
on Jan 15, 2016 at 2:21:28 pm

Hi,

Using CC '15 AME on a 2015 Macbook Pro 2.8/16 gig ram

I'm compressing footage to edit offline (from 422 to Proxy).

The Quicktime settings have the quality slider at 100, and it is greyed out - I can't change it - and i'd like to bring it down in the interest of space conservation. At least play around with it and see what it looks like at a lower quality value. Is it possible to change this setting? Would it save space?

I've also noticed that a number of settings in Quicktime in AME are greyed out under Video (except frame size). Does AME not want you to change Proxy values, or is it something I'm totally missing?

I'm super new to AME, having used Compressor for a long time, still learning my way around, so apologies.

Thanks!

If you're encoding ProRes the sliders grayed out because you can't change the data rates. The codec comes with the data rates embedded. if you're dropping down to ProRes Proxy with 1080p30 footage you're looking at about 45Mbps. This ProRes White Paper from Apple breaks down all the various data rates of each ProRes codec. There's a super handy table on pages 21-22 that lays out all the codecs, frame size, and frame rate options.
